Other mistake: While Lucy and Ethel are auditioning their act for Ricky at the club, just as Lucy spins around watch her hands as she very quickly pulls on the string at her waist, which causes her pantaloons to loosen and fall to the floor. (00:12:05)
Lucy Ricardo: Ricky, I'd like you to meet my second first husband.
Trivia: Lucy, Ricky, Ethel, and Fred all do the impressions of Maurice Chevalier. Thirty-six years later, the same impression is done in the 11th episode of The Simpsons.
